ISGRAPH(3)		 BSD Library Functions Manual		    ISGRAPH(3)

NAME
     isgraph --	printing character test	(space character exclusive)

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <ctype.h>

     int
     isgraph(int c);

DESCRIPTION
     The isgraph() function tests for any printing character except space.
     For single	C chars	locales	(see multibyte(3)) the value of	the argument
     is	representable as an unsigned char or the value of EOF.	In the ASCII
     character set, this includes the following	characters (with their numeric
     values shown in octal):

     041 ``!''	   042 ``"''	 043 ``#''     044 ``$''     045 ``%''
     046 ``&''	   047 ``'''	 050 ``(''     051 ``)''     052 ``*''
     053 ``+''	   054 ``,''	 055 ``-''     056 ``.''     057 ``/''
     060 ``0''	   061 ``1''	 062 ``2''     063 ``3''     064 ``4''
     065 ``5''	   066 ``6''	 067 ``7''     070 ``8''     071 ``9''
     072 ``:''	   073 ``;''	 074 ``<''     075 ``=''     076 ``>''
     077 ``?''	   100 ``@''	 101 ``A''     102 ``B''     103 ``C''
     104 ``D''	   105 ``E''	 106 ``F''     107 ``G''     110 ``H''
     111 ``I''	   112 ``J''	 113 ``K''     114 ``L''     115 ``M''
     116 ``N''	   117 ``O''	 120 ``P''     121 ``Q''     122 ``R''
     123 ``S''	   124 ``T''	 125 ``U''     126 ``V''     127 ``W''
     130 ``X''	   131 ``Y''	 132 ``Z''     133 ``[''     134 ``\''
     135 ``]''	   136 ``^''	 137 ``_''     140 ```''     141 ``a''

     147 ``g''	   150 ``h''	 151 ``i''     152 ``j''     153 ``k''
     154 ``l''	   155 ``m''	 156 ``n''     157 ``o''     160 ``p''
     161 ``q''	   162 ``r''	 163 ``s''     164 ``t''     165 ``u''
     166 ``v''	   167 ``w''	 170 ``x''     171 ``y''     172 ``z''
     173 ``{''	   174 ``|''	 175 ``}''     176 ``~''
